Good afternoon......I have a 73 olds 350 that im redoing with the number 8 smoger heads on it. I have a friend of mine thats going to be doing the head work and my Question is can i get some good proformace out of these looking for advice. Like what was done to make them flow better did you guys go with bigger valves from a bbo

Some other info going with speed pro flat tops , roller rockers, edlebrock rpm intake and cam, Stock qjet for now, headers,
I would love to have 400hp but 350 would be ok too.


Thanks Kris
